Abstract
The present invention relates to a kind of system for sending electric energy, the system includes being configured to supply electric energy to the power network of terminal user, it is characterised in that the power network is run with DC voltage.
Description
Technical field
The present invention relates to a kind of system for exchanging electric energy.The system of this commonly known as electric energy distribution network is
It is widely known.For many years, electric energy is transferred to terminal user by this network at generating, wherein under normal circumstances at generating
High alternating voltage is used between to the dispensing close to terminal user, and is sentenced from the dispensing close to terminal user
Middle low-voltage network is further sent.All over the world, low-voltage network is AC voltage network in practice in these, and it
Application 50 arrive 60Hz frequencies.Because standardization and people believe the dispensing electric energy mode especially in protective capability for a long time
There is advantage with low transmission loss aspect, so DC voltage dispensing is never generalized.
The content of the invention
However, it is an object of the present invention to provide a kind of alternate ways of above-mentioned alternating current dispensing, especially eliminating many
The defect of the individual supposition related to alternating current dispensing.
For this purpose, it is proposed that a kind of system for sending electric energy, the system includes being configured to electric energy
The power network of terminal user is supplied to, the power network is run with DC voltage.
For the ease of using this power network, the present invention further advises a kind of protection device for said system, described
Protection device is configured to the change of power consumption of the detection when connecting terminal user, and if the change is more than predetermined threshold
Value, is limited in power consumption during connection terminal user.
With wherein using the common protection device of curtage threshold value on the contrary, the excessive increasing of the power by detecting consumption
Plus, the excessive increase of the electric current of such as consumption detects irregular situation, such as undesirable short circuit or other excessive work(
Rate is consumed.Especially when this increase occurs suddenly and therefore step can be seen in power-consumption curve figure, according to
Present invention determine that occurring irregular situation.
This step form can easily be detected by monitoring the frequency analysis result of power consumption.This be because
The a large amount of harmonic waves occurred without when being included in gentle transition for step form.In a preferred embodiment, protection device therefore by with
It is set to according to measuring and there is harmonic current or component of voltage and detect change.In addition, the protection device can be configured to inspection
Power scale consume, and if power consumption be more than predetermined threshold if limit or disconnected end user connection.
Although there is available power in LF (low frequency) time domain, available power is not present in HF time domains.User can
Therefore be powered not according to square wave method but by ramping up method.In brief, harmonic wave HF (high-frequency) signal is not
There may be, because it indicate that occurring in that failure.
No available power interior in short-term, for example, in the situation of short circuit.When 10A electric current flowing and occur short circuit
When, 10A electric current still flows under 0 volt of voltage, so power is 0 watt.If electric current increase, then disconnected at the moment
Open circuit, from without producing spark, electric arc or not producing heat.
It is to allow failure progressively to upgrade according to the DC of prior art business industry ＆ solution, so that most weak partial failure,
The defect that wherein most weak part is typically the form of impaired fuse and also often damaged with semiconductor.
The present invention can set up a kind of efficient and reliable infrastructure.In normal conditions, such as in so-called hard net
Run like that in network, i.e., user can consume power in the range of they are allowed to.But if produce unpredictable electricity
Stream, this is counted as failure and the LVDC connectors of correlation will become no energy.
Protection, which is configured so that, observes the HF electric current behaviors with absolute nominal protection.This causes user to have to comply with
The energization behavior of determination is to ensure not activate the protection.
The invention further relates to it is a kind of in the system according to any one of the preceding claims to power consumption
The device of charging is carried out, described device includes being used for the connector of electric energy of the consumption from power network, electric energy is supplied to consumption electricity
At connector, the connector for manager's data communication with power network, metrology devices (device) and the data of energy connector
Unit is managed, wherein the metrology devices are connected to the consumption electric energy connector and the data communication connector and are configured
Into：At the time of the amount and monitoring electric energy for monitoring the electric energy consumed at exhaustion point are consumed；The data processing unit is connected to
The metrology devices and the data communication connector and it is configured to：Determined by the data communication connector in connection
When be available for the electrical power of consumption, determine consumed power by being connected to the metrology devices；Enable the data in output
Export the amount for the electrical power that consumption is available in connection.
In a preferred embodiment, it is this to be used to be connected to control member to the device that power consumption carries out charging, it is described
Control member is configured to：Set the desired value of power consumption；Consume the electric energy of desired value；When by being connected to the control member
User's actual consumption electric energy be less than the desired value when, supply of electrical energy to the energy snubber for being attached to the control member
Device, and when being connected to the electric energy of user's actual consumption of the control member more than desired value, from being connected to the control
The energy buffer of component draws electric energy.
Described device provides separation strict between power supplier's (network manager) and consumer (client) and (at least just counted
For) and cause private maximized advantage.Power supplier can be only seen consumption data and the available power level that communicates,
And whether user's unrestricted choice receives the available power.If using control panel, then consumer can form constant
Electricity consumption, so that user profile can not be obtained.Communication is driven rather than as in the prior art with business and energy supply herein
Controlled like that in the way of energy requirement drives.
Another aspect of the present invention is related to a kind of device, wherein the purpose in order to measure current level, is disposed with inciting somebody to action
Electric energy is sent to the measurement device of the first electrode series winding of the connector of consumption electric energy connector, and for the letter according to measurement
Number come cut off for the connector that consumes the electric energy from power network with electric energy is sent to consumption electric energy connector connector it
Between connection purpose and be provided with controller, and be disposed with and second to prevent the purpose of current level rapid fluctuations
The coil of electrode series winding.
This coil protects semiconductor, and for this purpose, this coil has sufficiently large value to ensure in short-circuit feelings
